LimeWire has requested a jury trial for their upcoming case against music publishers represented by the National Music Publishers Association.

NMPA will pursue $150,000 for each song that worked its way through the LimeWire P2P ecosystem, which could easily top out in the range of hundreds of millions of dollars.

“They seek to claim copyright or intellectual property rights as to works that are in the public domain and therefore not protected,” said Tonia Ouellette Klausner, a lawyer for LimeWire, when speaking to BusinessWeek.

LimeWire induced copyright infringement with their P2P file sharing software, according to the ruling by U.S. judge in a lawsuit filed by 13 record labels. Warner Bros, Arista, Capitol Records and more claimed that LimeWire users were able to exchange copies of more than 3,000 of their copyrighted recordings. LimeWire is now illegal.

The ruling was made against LimeWire by U.S. District Judge Kimba Wood in Manhattan, and the lawsuit was originally filed waaaay back in 2006. She decided that LimeWire and Mark Gorton had committed copyright infringement, engaged in unfair competition and induced users to commit copyright infringement with the software.

LimeWire came to fame as another one of those P2P (perr-to-peer) file sharing programs based on the Gnutella network, that allowed users to download music, movies and more for free. Later they also joined up with BitTorrent. They were sued in 2006 by an RIAA umbrella group; a month later, LimeWire countersued, citing antitrust violations.
